Umthelela Wezinto Ze-Pe Ezisetshenziswa Zesikhwama Sokupakisha

Ukuthandwa kwezinto zokusetshenziswa ze-PE esikhwameni sokupakisha izinto zokusetshenziswa!Izinto zokusetshenziswa ze-PE zibalulekile emaphaketheni.Uma ufuna ukuvala izikhwama zokupakisha, i-PE kumele yengezwe ezintweni ezingavuthiwe.Akusho ukuthi izinto zokusetshenziswa ze-PE ziwukhiye!Ukuthandwa kwezinto zokusetshenziswa ze-PE emaphaketheni:

1. Incazelo evamile yezimpawu ze-PE:

Ngokuvamile, ukubonakala kwesikhwama sokupakisha se-PE eluhlaza kubonakala ngokuphelele, kodwa kunomuzwa wenkungu;ithambile uma uyithinta futhi ine-ductility enhle;ukumelana nokushisa okuphansi nokumelana kwamanzi okuqinile, kodwa uma kuqhathaniswa ne-O2, izinga lokuvimbela igesi liphansi;Noma ukuxazulula, ingaphrinta ubuchwepheshe obumpunga obukhanyayo, obunganconyelwe ukupakishwa okukhulu kwekhofi elimnyama lokuphrinta.

2. Ukuhlukaniswa kwempahla eluhlaza okwejwayelekile kwezikhwama zokupakisha ze-PE emaphaketheni angaphandle:

Inqubo yokukhiqiza ye-PE, i-PE ingahlukaniswa ngezigaba ezintathu: i-HDPE.I-HDPE inokuminyana okuphansi, i-LDPE inokuminyana okuphansi, ukuminyana okuhlobene komugqa kuphansi, kanti i-LLDPE iphansi.Isicelo sabo sigxile emasakeni okupakisha ahlukile, futhi izici zabo nazo zihlukile.I-HDPE impahla eluhlaza inokuminyana okuphezulu okuhlobene, eyaziwa nangokuthi i-low-voltage high-voltage polyethylene, futhi inokumelana okuhle kakhulu nokushisa okuphezulu, ukumelana nokushisa, ukumelana ne-asidi ne-alkali nezinye izici.ungqimba olusobala.

Impahla eluhlaza ye-LDPE enokuminyana okuphansi ibizwa nangokuthi i-polyethylene, okuwuketshezi oluthambile lwe-PE.I-cocoa ingasetshenziswa ngokuqondile njengezikhwama zokupakisha, njengezikhwama zokuthutha zezithelo ezintsha, inyama kanye nezinye izimboni zokudla zamafriji.Noma izikhwama zepulasitiki, izikhwama zefilimu, njll. zokuthenga ukudla.

Izinto zokusetshenziswa ze-LLDPE ezinomugqa ophansi wokuminyana: zifana ngokubukeka ne-LDPE, izinga lokushisa eliphansi ductility, ukumelana nomthelela, ukumelana nokuqhekeka kwenkundla yengcindezi, ukumelana nokukhathala, lesi sici sihle uma kuqhathaniswa.Sebenzisa u-ayisikhilimu woqobo we-LLDPE, u-ayisikhilimu, amabhola enyama, amadombolo aqandiswe ngokushesha nezinye izikhwama zokupakisha, bese usebenzisa isendlalelo sokungenisa ukushisa sezinto zokusetshenziswa ze-LLDPE.

3. Izindlela ezihlukene zokupakisha izikhwama ezinokuminyana okuphezulu kwezinto zokusetshenziswa ze-PE kanye nokuminyana okuphansi kwe-PE:

1. Uma isandla sintekenteke, singathamba, futhi izinto ezinobukhulu obuphansi zithambile.

2. Lapho unwaya izinto ezingavuthiwe ngozipho, akulula ukushiya imihuzuko.I-HDPE impahla eluhlaza, i-HDPE enobuningi obuhlobene nesihlobo, kanye ne-LDPE enokuminyana okuphansi kwesihlobo.
